Title Case converter

A title case converter is a contract with the reader: important words stand up, glue words sit down. Most online converters implement one unnamed hybrid. This one lets you choose AP, APA, Chicago, or MLA, then overlays brands so Html becomes HTML.

What Title Case is (and is not)

Title Case is for headlines, chapter titles, navigation labels that should feel published, and documentation H1s. It is not ALL CAPS (UPPER CASE), not “every word capitalized” (Capitalized Case), and not everyday prose (Sentence case). Playful modes such as alternating case or inverse case are for memes and toggles — not publication titles.

Example paste: the quick brown fox jumps through the fence

• AP Title Case → The Quick Brown Fox Jumps Through the Fence (four-letter Through rises)
• Chicago often keeps longer prepositions quieter
• Capitalized Case → The Quick Brown Fox Jumps Through The Fence (The / Through both rise)

Pick the guide your editor, school, or brand book names. First and last words are always capitalized in every guide on this page.

Style comparison table (AP / APA / Chicago / MLA)

Same headline, four small-word philosophies. Exact house manuals add exceptions; this table shows the practical differences most writers hit.

Example fragment	AP	APA	Chicago	MLA
through (4 letters)	Through	Through	through	through
with (4 letters)	With	With	with	with
between (longer prep.)	Between	Between	between	between
the / and / of (inside)	lowercase	lowercase	lowercase	lowercase
First or last word is the	The	The	The	The
Hyphenated follow-up	Follow-up (short trailing minor)	Follow-Up (major segments)	Follow-Up	Follow-Up

Quick chooser

• AP — news, press releases, many web newsrooms; prepositions of four or more letters usually rise.
• APA — academic social-science titles; close to AP on short prepositions, with academic subtitle habits.
• Chicago — books, some magazines; longer preposition list stays lowercase inside the title.
• MLA — humanities coursework; small words stay small unless they begin or end the title.

AP title case converter

Pick AP in the Title style control. AP generally capitalizes prepositions of four or more letters (Through, With). That is what people mean by an AP title case converter. Chicago keeps more prepositions lowercase. APA and MLA sit between those poles.

After the style pass, smart casing restores brands and acronyms so NASA, iPhone, and JavaScript keep their conventional shapes. Turn smart casing off when you need a purely mechanical result for a style audit.

Edge cases writers ask about

Hyphenated compounds. Chicago-style paths capitalize each major segment (State-of-the-Art vs quieter minor parts depending on the guide). AP is more likely to keep a short trailing minor segment lowercase (Follow-up). When a hyphenated term is a brand, leave smart casing on.

After a colon. Subtitles are common in academic and book titles (Climate Policy: A Field Guide). Capitalize the first word of the subtitle in every mode on this page so the clause after the colon reads as its own title unit.

Short words at the edges. A Study of Light and Light of A both keep the edge words large. The small-word list never wins against “first or last.”

All-caps pastes. If the draft arrived as THE QUICK BROWN FOX, run lower case or rely on this Title Case pass (it lowercases before applying style rules), then pick your guide. Do not leave ALL CAPS in a CMS title field and expect SERPs to look friendly.

Acronyms and product names. Smart casing restores NASA, iPhone, JavaScript, and similar dictionary terms after the style pass so you do not ship Nasa or Iphone in a headline.

Possessives and apostrophes. Word-initial letters still capitalize (Editor’s Note). The apostrophe does not break the token the way a space would.

When to use Title Case

Use this page when you are writing:

• Blog posts, news headlines, and magazine-style titles
• Academic or publication titles that must match AP, APA, Chicago, or MLA
• Docs H1s that should look intentional, not like Start Case
• SEO titles where readable capitalization helps scanning in SERPs

Skip Title Case for UI body copy, emails, and error messages — prefer Sentence case. Skip it for playlist titles and form labels that want every word standing — use Capitalized Case. Skip it for mock or meme casing — use alternating case.

Title Case in Word, Excel, and Google Docs

Microsoft Word has Change Case → Capitalize Each Word. That is Start Case, not AP/Chicago Title Case: short words such as “of” and “the” get capitalized too. Word does not ship AP or Chicago small-word lists.

Excel has =PROPER(A1), which is also Capitalized Case per cell — fine for names, wrong for style-guide headlines.

Google Docs → Format → Text → Capitalization → Title case likewise capitalizes each word without AP/Chicago exceptions.

When you need real style-guide Title Case, paste the draft here, pick AP / APA / Chicago / MLA, copy, and paste back into Word, Docs, or your CMS. Nothing is uploaded. Step-by-step Change Case / PROPER / Docs notes also live in how to change case in Word, Excel, and Google Docs.

How to use this converter

1. Paste or type the headline in the editor above (or drop a .txt file).
2. Choose Title Case if you arrived from another mode, then pick AP, APA, Chicago, or MLA.
3. Leave smart casing on unless you want a strict mechanical pass.
4. Copy with the button or Ctrl/Cmd+Enter. Download a .txt if you need a file.

Your paste stays in this tab’s session, so you can jump to Slugify for a permalink or to Sentence case for the lead paragraph without copying again.
